I'm completely in the same boat here. My car looks completely gleaming and stunning. But in seeking prefection, I can see the swirl marks under intense light sources when viewed at an angle (bright sun, street lamps). I bought turtlewax colour magic plus which was ok, but only temporarily reduced the appearance of the swirl marks. After reading all the backs, those small tubes seemed to be the right stuff, but like the other guy said, am I supposed to use this over the entire surface of my car? I may even need two tubes in that case!
